BRICKMAKING MACHINE Filed Feb. 18, 1928 4 Sheets-Sheet '4 Patented Aug. 30, 1932 OFFICE LOTT D. OLIVER, OF HOUSTON, TEXAS BRICKMAKING MACHINE Application filed February 18, 1928. Serial No. 255,429.

This invention relates to new and useful improvements in a brick making machine.

One object of the invention is to provide a brick making machine, a novel type of mould, whereby a plurality of brick may be pressed, or moulded, in a unit, with weakened lines along which the unit may be easily broken up into individual brick, having roughened, or irregular faces.

Another object of the invention is to provide, in a brick press, a mould having means for forming weakened lines separating the brick, of'whicha moulded unit is composed so that the unit may be easily broken into individual brick, said means being of such disposition as not to interfere with the removal of the moulded unit from the mould.

A further feature of the invention resides in the provision of means, associated with the 2!), press for ultimately separating the moulding units, along said weakened lines, into individual brick, or building units.

With the above and other objects in view this invention has particular relation to cer- 2 2 tain novel features of construction, operation and arrangement of parts, an example of which is given in the specification and illustrated in the accompanyingdrawings wherein Figure 1 shows a longitudinal vertical sec tional view of the mould.

Figure 2 shows a plan view thereof.

Figure 3 shows a sectional View of the mould with the cover removed. 1

Figure 4 shows a longitudinal vertical sectional view of the mould, showing the cover disposed above the mould box, and illustrating the parts in position for discharging the pressed unit from the mould.

Figure 5 shows a perspective view of the pressed unit composed of a plurality of brick integrally joined together.

Figure 6 shows a perspective view of an individual brick produced from said mould.

Figure 7 shows a fragmentary side elevation of the apparatus for separating the moulded unit into individual bricks.

Figure 8 shows a vertical sectional View thereof, and

Figure 9 shows a horizontal sectional View of the complete machine.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1 designates the mould box, of rectangular contour and having the sides 2, 2 and the ends 3, 3. The sides 2 of the mould box have the opposed inside vertical ribs 4, 4, which continue across the bottom 5, of the box, forming the transverse bottom rib 6. The ends 3 of the box, have the inside oppositely disposed ribs 7, 7, and the bottom 5, has a lengthwise bearing slot 8 aligned with the ribs 7.

There is a plunger 9 forming the top or 5 cover for the mould, and which is adapted to fit closely into the mould box and whose under side has the transverse and lengthwise ribs 10, 11 aligned with the respective ribs 4 and 7. 1

There is a lengthwise blade 12, adapted to work through the bearings slot 8. The upper edge of this blade is beveled to an edge, as is also the free edges of the ribs 4, 6,7, 10 and 11. The bottom 5, of the box is fixed to the upper ends of side arms 13, 13 which, in turn, are mounted on the vertically movable table 14, while the mould box 1 is fixed on the frame 15, of the press. The blade 12 is mounted on the coil springs or other yieldable seats 16, which in turn are supported by the table 14, and normally the sharp edge of said blade projects above the upper surface of the mould bottom 5 with the stops 17 carried by the said blade resting against the under side of 85 said bottom.

Fastened to, and depending from the blade 12 are the tubes 18, 18 which extend down through the openings 19, 19, in the table 14. The lower ends of these tubes have the bear- 1 ing glands 20 20, screwed therein having central'bearings through which the release rods,

21, 21 work. The upper ends of these rods, Within the tubes 18 are enlarged, forming plungers 22, 22 'andthe lower ends are attached to a stationary part 23, of the press.

In operation the mould box is filled with plastic clay, or'other material of'which the brick-is to be formed and the cross head 24,

carrying the plunger is then lowered, by the compacted, will" have-oppositely disposed grooves formed by the ribs 6 and 10 ;"'a1 s0uie I lengthwise top and bottom grooves, and theconnecting end 'groove's,'formed bytherlbs vertical side grooves formed by the ribs 4 and into individual brick, as hereinafter eX' plained.

Underneath the platform 26 are the length-' wise and transverse blades 39, 10 which are lntegrally joined together at their centers and which are aligned with the corresponding bolted to the underside of the platform26. The unit formed by the blades 39, has

poseto be hereinafter stated; 3.

The housing ll has a central vertical bearing43 through which the rodee works. The

the, aligned top and bottom; transverse upper end ottherod is attached to-and sup- 11, the blade 12 and merits 7 ,7 .1

.When the material is sufficiently com-e pressed the plungerQ'is elevated and thebotr tom 5 is 'raised,- by the table 14, until its"upper 'surfaceis flush withthetop of'themould box. As thetableis raised the blade 12 will move 54 upwardly with it untilthe'glands 20 contact with the lower ends of the plungers 22 andv the upward movement of sa'idblade will be I bottomof themould boigonto the adjacent f platfo n arrested but the bottom will move on upwardly until the compressed unit 25: clears 30 the upper edge ofsaid blade, and saidunit maybe then discharged laterally "from'the {For the purp'oseof discharging the com-f pressed unit 25 em the mouldboxonto the platform 26a plu wer 27 is provided which Q is operable through the connecting; rod :28, i one end-of which is pivoted to'the plunger 27 ,and whose other endhas an eccentric connection with the constantly rotating driving disc 29 which fixed on the drive shaft 30; The

The rod 14 and spring are enclose'd by means of the hood 47 which is bolted tothe underside of the housing 41""and' which has the lower endbearing 48 through which said 3 rod 44 a'lsoworks'. I p I "The lowerend of the rod 4:4: abuts the U- shaped bracket 49, the ireeends ofwhose arms are outwardly turned, formingfthebearings V 50, 50andfbolted to the"und'erside' ofgthe' platform 26are the bearingmembers 51, 51 towhi'ch the respective arms"52,j52:are piv-' oted.- The inner ends ofthese arms are up-rv f i turned a'ndwork underneath and in contact g with the respective bearings50 'and'their;

having" the central depending pilot spilie '53 face of which the 'supportingfplate' 61*;isf bolted andsecured to the lower end of the plate 61 there is an enclosing hood 62fha'ving aligned 'upper' and lower end bearings 63'; 64 through whichthe rod 56 works. Within the housing" 62 there is an adjustablespring 1 seat 65 'and between this seat and the lower end of the housing 62there is *a coil spring 66, which normallyholds the blades 57,153

spaced above the unit'to be separated riedbythejlower end fof the rod '69; This rod "69 through the upper and lower 1'10 and 58,al ig'ned over-the corresponding blades" 7 39 andetl, The blades 57, 58 form annit end bearings 70, 71 of the housing 72 which is bolted to the upper end of the supporting plate 61. Attached to the rod 69, within the housing 72 there is a stop 73 which limits the downward movement of the rod 69. and above this stop the rod 69 carries an adjustable spring seat 74. On this seat and sur rounding said rod there is a coil spring 75 whose upper end bears against the upper end of the housing 72.

The upper end of the rod 69 carries a cross pin 7 6 with the ends of which are spaced cams 77, 77, fixed on the shaft 7 8, successively contact. The shaft 78 rotates in the bearings 79, 79, which are fixed to the upper part of the support 60. The shaft 78 is constantly rotated to the end that the cams 77 will alternately elevate the rod 69 to place the spring 75 under compression and then release said rod to the influence of said compressed spring.

. When the rod 69 is so released the spring 75, assisted by gravity, will impart a downward thrust to the rod 69 and the head 68 carried thereby will strike the head 67 underneath and this will drive the blades 57 and 58 downwardly into the corresponding grooves in the upper face of the unit 25 onderneath, the pilot spike 59, first entering the upper face of the unit at the junction of said grooves. At the same time a downward thrust will be imparted to the bracket 54 and it will act through the arms 52 and bracket l9 to impart an upward thrust, through the rod 44, to the blades 39, 40 and force them into the unit 25 along the lengthwise and transverse grooves in the under face thereof, and the pilot spike 42 first entering the unit 7 at the junction of said last mentioned grooves.

The mechanism is so timed that the blades will be successively actuated only as the units 25 are successively delivered onto the plat form 26, from the mould box and is further so timed that the upper and lower blades will operate against the moulded units at exactly the same time. The pilot spikes and blades will thus separate each unit 25 along the weakened lines into individual brick which may then be removed from the platform 26 manually or by any suitable means provided for the purpose. As the unit is thus separated by the blades the guides 21 will yield outwardly as the individual brick are moved apart endwise.

While I have shown what I now consider the preferred form of the device it is obvious that mechanical changes may be made therein, and equivalents substituted for the parts shown and I reserve the right to make such changes and modifications in the mechanical structure as may be comprehended within the scope of the appended claims.
